Hi,

I'm using AN86233_DeepSleepADC.cydsn project, but the current is about 1.8mA insted of 9uA as read in comments of project. Someone can explain me the reason?

Tanks in advance!

Hi @saga_1136906

Additionally, can you create a new project which just sends the device to deep sleep and let us know your measurements in this case? 

Were you able to measure the current with just the deep sleep API in an empty project? This would provide a rough idea about the current consumption when no components are enabled. A high current in this stage would point towards leakage current in the board. Also, please ensure that the debug select in the Systems tab in the DWR file is set to GPIO.

Thanks and Regards,
Rakshith M B

Hi @saga_1136906

Can you please provide further information regarding your setup? Which target device are you using and how are you measuring the current?

Additionally, can you create a new project which just sends the device to deep sleep and let us know your measurements in this case?

Hi, 

I use CY8CKIT-042-BLE Pioneer baseboard. With CY8C4247LQI-BL483.

The project is pratically unaltered

Thanks
